Very true - also, this being their technical report, I'd personally be surprised if there wasn't some amount of technical jargon present, sufficient to establish the facts of these events. All they do is identify a set of sophisticated actors who have tradecraft and technical expertise to rival a nation state, and then further established a series of similar attacks have been conducted on targets of Russian foreign interests by these same groups. Short of an indictment a la Chinese hackers, or declassification of the information pertaining to the attacks (something that's apparently being prepared), there are not facts present to make a formal attribution.
